APPARATUS FOB CLEANING PLATE-GLASS POLISHING RUNNERS.

Application filed March 23, 1923. Serial No. 627,084.

The invention relates to apparatus for polishing` plate glass andparticularly to that form of apparatus in which the glass 'to bepolished carried beneath a series ot polishers on cars or other carrierapparatus. After a certain iieriod ot' use, the toits o t the runnersbecome calmed with 'the rouge or other polishing nuiterial and theirefticieney is reduced. The principal object of the present invention isto provide` a simple, convenient arrangement i'or washing the Jfelts o ithe various machines at intervals' without interfering with thecontinuous operation of the apparatus,

In its preferred 'torni the apparatus com prises a 'pan mounted forn'iovement longitudinallgY ot' the series ot polishing` machines andadapted to be moved beneath each setot 'runners carried by each machine,the runners being tirs-t raised to permit the positioning oft the pan asto receive them. The cleaning may be accomplished by rotating therunners in a cleaning liquid in the poner by applying jets ot' waterupward from the bottom o-l the pan against the lower faces of therunners, ln either ease, nieehauica'l means such as brushes may beemployed to assist in loosening the rouge from the telts. Certainembodiments of the invention are illus,

trated in the wherein: 4

Figure l is 'transverse section through the ajjiparatus showing the'meshing devices in position l'or use. Fig. 2 is a plan View ot a part;ol' the apparatus with the washing derice removed. Fig. 3 is a plan viewof the washing' dei/ice by itself. Fig'. l is'an enlaruedtransverse'seetion'through u part of one side ot the apparatus. and Fig.5 is an enlarged transverse section through a modified form ot'construction.

Referring to Figs. l'and l?, l-l are a serits ot tables or trut-ltsmounted upon the. track il and carrying' a series of sheets of glassplaced end to end which are to be polished. Arranged in series above thetables or trucks are a series of polishing machines. two of which areillustrated in Fig. These polishing machines comprise a siu'iportiug`trziimeivorlt E made up ot commerciai sei/'tier as illustrateth andcarrying the rotatirff" "frames i'ww-t upon which the polishiuu mers arecarried. The run ners curr the polishino,` telus ti upon their lower sil. mul are .mounted upon spindles 7 accompanying drawings slidablevertically through the frames l so that the weight ot the runners isimposed upon the glass when the supporting frames are lowered. Thetrames 4 are rotated by m xuns ot' the spindles S provided with the spurgears J and driven from the pinions lt). llach machine preferably hasits own operatiuu' motor 1l mounted upon the top of the framework andarranged to drive the spindle t through the belt l2 and gears i3 andl-i; the latter ot which is keyed to the shaft l5 which carries thepinion itl. The method of driving the spindles 8 is immaterial in so taras the present invention is concerned.

Provision is made 'ior raising and loweriurv the ruimer 'Frames h'l hymeans ot the levers ltl pivoted upon the brackets 1T and engaging thtthrust hearing member itl, the upper hilt' of which secured to the shafto. The outer end oi the lever is provided with the threaded rod 19 whichis moved up and down thri'iugh the nut 2() carried upon the bracket 2lby means ot' the hand wheel 'l'his part of the apparatus is employed inraisinmr and lowering the runners to permit. ot' the washing operation,as hereinafter described. Any other desired means might be employed torsecuring this vertical movement ot the runners.

The Washing:r device consists et .the pan preferablyY in the form of acasting carrying upon its bottom the pertoratei'l spiral pipe 2l and thebrushes rl`he pan is mounted upon four wheels or rollers Q6 and theserollers are carried upon a trad; 2T extending` longitudinally ol theapparatus. lVater is supplied to the spiral pipe from the pipe 2S havingthe controlling valve 2i) and connected to the flexible pipe 30. lnordc'r to position or index the pan in proper position, it is providedat its sido edges with a pair ot pioneers Si normali)Y pressed down hythe springs 32 and adapted to cir rage recesses suitabl;r located in therails 2T. In order to prevent splashing' from the machine during thewashing operation. the shield l-'l is preterabhr employed, si-eh Kshieldbeing made in two or more seeth and applied to the pan utter it is inposition i'or use. The shield is inclined as indicated in lille'. and isheld in position hy means. ot

`brackets 35 whose lower ends `engage :i

groove extending' around the periiihery oi' the pan. The shield 3lispreferably made in two or more sections, which are removed llt) bylifting them vertically, thus withdrawing thc lower ends of the bracketsla l(Fig. l) i'roni the `groove `in the edge ot the pan. The pan isprovided with a suitable drain pipe '36 for removing' the mixture ot'ivater and rouge which collects therein.

ln carrying out the Washing operation, the pan is nioved successivelyunder the series of runner 'l1-ames, vthe washing occurring at intervalssuch as are found necessary in order to keep the i'elts in properWorking condition. lIn order to position the pan between the runnertrame l and the glass carried on the tables therebeneath, this runnertraine is raised by means of its lever 16 to a height such as to permitthe pan to be run between the glass and the runners, atter which theshield 25% is placed in position and the valve 29 leading to thefspiralpipe opened so that the vvatcr trom lthis pipe is directed upwardlyagainst the lower faces of the t'elts. At this time the runners arelovvered so as to bring their faces into contact with the brushes 25,thus loosening' the` rouge upon the telt and speeding up the cleaningoperation. The spindle carrying the runner trame and runners continuesto revolve so that the felts are carried across the brushes and past thesprays of water from the pipe 24. lt desired, the outlet from the drainpipe 36 may be closed so as to provide a bath ot liquid in the pan inwhich the lelts rotate. After the telts are suiiiciently cleaned, therunner trame is raised., the shield 3l removed and the Washing pan movedon to the next machine Where the cleaning cycle, as above described, isrepeated. lt will be seen that the cleaning ot the successive runnersot' the series may be carried on without discontinuingy the polishingoperation of the series as a Whole7 only one runner being out 'ofcommission at any one time.

Fig. 5 illustrates a modification in which the brushe: 25 otl Fig. l areremoved and in place thereot the metal at the bottom ot' the pan isroughened, as indicated at 37, for engaging the lovver faces of the:telts in order to loosen the rouge. Various other means might beemployed for securing the applicaltion of liquid to the bottom ot' therunners and for mechanically engaging the felts 'to loosen the rouge.
